Purpose: The purpose of this qualitative study was to explore the experiences of post-traumatic growth in breast cancer survivors by applying grounded theory methods. Methods: Participants were seven breast cancer survivors who had been diagnosed with stage I or higher breast cancer, had completed acute treatment, and were members of an internet self-help group for breast cancer survivors. Data were collected through individual in-depth interviews from July 11, 2022 to May 4, 2023. The interview contents were transcribed and analyzed using Corbin and Strauss’s grounded theory method. A total of 18 sub-categories and 9 categories were identified through the open coding process. Results: As a result of axial coding based on the paradigm model, the central phenomenon of post-traumatic growth experiences of breast cancer survivors was revealed as ‘Finding true life after the pain of death’. The core category was identified as ‘Promise a life without regrets’, which consisted of a four-step process: reflection period, recovery period, transition period, achievement period. Breast cancer survivors experienced restoration of their inner selves, strengthening of positive thinking through the process of resetting their life values and goals, and pursuit a stable and satisfying life. Conclusion: To help breast cancer survivors grow after trauma, the importance of accepting changes in their bodies and maintaining a positive perspective was highlighted.

The purpose of this study was to analyze the breast growth variation trends and characteristics of Korean adolescent girls based on 3D body measurements. Subjects were 174 girls aged between 13 and 18. 3D body scanning data were collected and the data were measured by Geomagic Design X program. The total of 18 anthropometric measurements and 4 index items were analyzed. The main results of this study are as follows: 1) Overall, the breast growth of adolescent girls got out of children's body shapes at the age of 14 and the adult's body shapes appeared remarkably at the age of 18. Before the age of 15, the adolescent girls' breast enlarged. 2) The surface lengths of upper body, which means the breast volume, showed significant growth above B cup groups rather than under A cup groups. The demand of B cup size (32.2%) was higher than A cup size (25.9%). And 35.6% of subjects' brassiere band size was 70. 3) The thorax grew evenly in the circumference, depth and breadth. The thoracic development related to the breast volume as well as the whole upper body's development. These results reveal that it is necessary to develop adolescent girls' brassiere reflecting on adolescent girls' breast growth variation trends and characteristics by age, breast size and thoracic development.
